ok so you talk about live objects, i see. Nonetheless I assume that it will still install NBOpenGL fully without any problems. The problem is instance objects that I may be using at the time. -- View this message in context: http://forum.world.st/NBOpengl-Error-IcompatibleLayoutConflict-tp4707721p47… Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

how to produce pharo-based distribution?

by Tudor Girba

Hi, Are there scripts available to build bundles for each platform (Linux, Win, Mac) like the Pharo 2.0 ones? I am looking for something similar for Moose. Cheers, Doru -- www.tudorgirba.com "Every thing has its own flow"

Re: [Pharo-dev] cannot commit with gofer to sthub (HTTP 403)

Hi, Yes, I know that. I was just saying that I tried multiple variations just in case someone wanted to know. The debugger is not particularly helpful here: I just get a 403 response which means that the authentication fails. I cannot see where the problem is.

Fwd: NBFFI version of the OpenDBXDriver

by Rocio Amaya

* Hi! * * I'd like to show a bit the outcome of the first iteration of the DBXTalk Gsoc of this year. First, I've been adapting myself to the environment and technology (DBXTalk, OpenDBX, TalkFFI), and I've written some little tutorials of what I've learnt about them: - Post of how to install OpenDBX http://rochiamaya.wordpress.com/2013/07/28/how-to-install-version-1-4-6-of-… - Post of how to install and use TalkFFI to generate mappings http://rochiamaya.wordpress.com/2013/07/30/create-bindings-with-talkffi/ - Post of how to use mappings generated by TalkFFI http://rochiamaya.wordpress.com/2013/08/06/how-to-use-the-generated-binding… Also, as concrete code, we have built a NBFFI version of the OpenDBXDriver. The main idea of this is to provide a backward compatibility layer to people that use OpenDBX, while letting us move forward dropping the old FFI implementation. Gofer it smalltalkhubUser: 'DBXTalk' project: 'Configurations'; configurationOf: 'OpenDBXDriver'; load. (((Smalltalk at: #ConfigurationOfOpenDBXDriver) perform: #project) perform: #version: with: â1.3â) load: 'DeveloperGroup'. However, the configuration still supports to load the former version of the driver (no NBFFI) Gofer it smalltalkhubUser: 'DBXTalk' project: 'Configurations'; configurationOf: 'OpenDBXDriver'; load. (((Smalltalk at: #ConfigurationOfOpenDBXDriver) perform: #project) perform: #version: with: â1.3â) load: 'FFIDriver'. And the configuration with only NBFFI version. Gofer it smalltalkhubUser: 'DBXTalk' project: 'Configurations'; configurationOf: 'OpenDBXDriver'; load. (((Smalltalk at: #ConfigurationOfOpenDBXDriver) perform: #project) perform: #version: with: â1.3â) load: 'NBFFIDriver'. To use, writte in the Workspace and DoIt: âto set the NBFFI bindâ LibOpenDBXMap initialize. OpenDBX current: NBPharoOpenDBX new. âor to set the oldFFI bindâ OpenDBX current: FFIOpenDBX ffiImplementationForOS . In our current/next steps, we are starting to dig into the other driver implementations. I'm currently working in a Mysql driver implementation that will use the C mysql library directly without the intermediation of OpenDBX. That way, the setup of the environment will be far easier and the entry barrier will be lowered. Best Regards!* *Rocio.*

Re: [Pharo-dev] NBOpengl Error : IcompatibleLayoutConflict

by Camillo Bruni

Well no it is an error since the classes are in an invalid state. It is not possible to do all migrations with Monticello and keep all classes in a sane condition all the time. Just image moving an instance variable from a subclass which is in one monticello package B to a superclass which is in another package A. If the default load order is A - B then you will have all of a sudden a double variable declaration. In any case, the old class builder was very permissive and it even let you continue to work with classes with invalid layout states (for instance the duplicate variables, or incompatibly subclass layouts). For as long as you don't have instances and you do not use these classes there is not really a problem.

Re: [Pharo-dev] NBOpengl Error : IcompatibleLayoutConflict

So this mean this is more of a warning than an error and it does not really affect the installation of NBOpenGL ? and what it means by "invalid state for a small period" ? is that a bytecode issue or an object issue ?
